Description
Unique tape casting process with appropriate molecular weight and ion exchange capacity of perfluorosulfonic acid resin is used to form homogeneous membrane with uniform thickness It is widely used in electrolytic chlorine dioxide generator, etching solution recovery copper, gold salt preparation, amino acid refining, caustic soda preparation, electrodialysis and other electrolytic industries.
◮ Thickness and Basis Weight Properties
◮ Physical and Other Properties
◮ Hydrolytic Propertie
◮ Measurements taken with membrane conditioned to 23°C, 50% RH.
◮ Conductivity measurements a 23 °C, 100% RH.
◮ A base titration procedure mea sures the equ ivalentsof sulfonic acid in the polymer, and uses the measu rement to ca leu late the acid capacity or equivalent weight of the pure polymer.
◮ Water content of membrane conditioned to 23 °C and 50% RH (dry weight basis).
◮ Wateruptakefromdrymembraneto conditioned inwaterat 100 °C fori hour (dry weight basis).
